HLS stream, error when trying to switch streams too fast from player

Wowza Streaming Engine
1

Hi,

I’m trying to achieve making a player where you can switch live HLS sources quickly (using videogular to be accurate). If I switch sources slowly, like waiting for 5-6 seconds, everything works. But, when trying to switch sources faster, the server sends a 403 Forbidden error. I think it’s something like a security measure to prevent users flooding the server, but in my use case, it’s really problematic.

Is there a way maybe to authorize this use in the control panel ? I haven’t found anything…

I’ve found this in the Wowza log when the error happens :

HTTPStreamerAdapterCupertinoStreamer.onPlaylist[live/1/playlist.m3u8?DVR]: Invalid session

Hello!

Thanks for contacting the Wowza Community!

Confirming this is for a Live stream?

Looks like you are also using nDVR. Are you switching to a archived stream or a current live stream?

Do you have any security enabled on the server that would cause a 403 forbidden error?

Might be best also to open a ticket HERE and provide the following:

Hope this helps.

Regards,

Jermaine

Hello,

I’m having exactly the same problem with a default server and the default vod application on WowzaStreamingEngine-4.7.1 with a developer licence, my server is a relative clean Unix Debian Jessie (I also tested on my local Winodws 7 system).

I get an error after calling and streaming a video more than 10 times in a row (every 4 sec for exemple), same problem with different videos on each call.

For exemple, if I run the Test player from the Engine Manager (tested with HLS, MPEG DASH, HDS), and click on Start and Stop buttons with the default sample.mp4, after the 10th time, I got an error: “Status: Source stream or file could not be found or access was denied.”

On the server side, at the same moment, I get this line in the /usr/local/WowzaStreamingEngine-4.7.1/logswowzastreamingengine_error.log: (First line is the error with HLS, second with MPEG DASH, third with HDS)

WARN servercomment 2017-12-05 15:53:35-----17.952--------HTTPStreamerAdapterMPEGDashStreamer.onManifest[vod/mp4:sample.mp4/manifest.mpd]: Invalid session

WARN servercomment 2017-12-05 15:55:58-----161.226--------HTTPStreamerAdapterSanJoseStreamer.onPlaylist: Invalid session

Do you have any idees what is causing this problem ? is it maybe due to the developer licence ? Can you help me ?

Thank you for your answer.
